OSMF SVN

1) SMILPlugin - SMILMediaGenerator class modified to support both live and vod smil files. SMILLoader modified to retain original resource metadata.
2) AkamaiBasicStreamingPlugin refactored. This includes improved support for all types of streams while the plugin is loaded, added support for plugin metadata that can override built in defaults for a) live stream time out; b) whether or not the plugin should try to reconnect to a live stream if both primary and secondary encoders fail; c) the interval at which the retry should occur. Added support for resource metadata for specifying connect-level and stream-level auth tokens so that these tokens do not need to be part of the URL (although this is acceptable also).
3) AkamaiPluginSample app updated to support auth tokens which are not part of the URL (these are passed to the Akamai plugin via resource metadata).

Minor cleanup, fix typos.

Better fix for serial seek trait event order bug. Also fixed bug in MediaPlayer where currentTimeChange event could be dispatched on trait addition, even if currentTimeUpdateInterval was zero. Added unit tests for SerialElement holding DurationElements, since that case exposed quite a few edge case bugs.

Fix compiler warning by adding a blank CSS file.

Fix various issues related to serial seek event order, and loading of children when transitioning from one child to the next. Exposed while testing a SerialElement with DurationElement children. Updated unit tests.

Fix bug where autoRewind false wasn't being respected.

Minor cleanup. Add timed image example.

Fix for FM-396.

Fix for FM-348:

Once a video or audio element is loaded, its default time trait is overridden by the permanent versions. However, not all elements have their correct duration set until they are played back. Video elements get their durations from a metadata event that's triggered after play back, for example. To remedy the element's duration going to NaN in between the default trait being removed and the permanent trait being properly set, the NetStreamTimeTrait is extended to take a defaultDuration member. Video and audio elements now forward their default duration value to the trait.

Reenable MediaPlayer+DurationElement tests. Separate testing of MediaPlayerStateChangeEvents from other events, since the state change event usually fires later.
